[Mechanism of blunt spleen injury: a finite element analysis].

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo explore the biomechanical mechanism of blunt spleen injury based on finite element analysis.
objectiveA fist finite element model was used to simulate the impact at 4-8 m/s in the spleen area of THUMS4.0 human body model from the front of the left costal area, the left anterior axillary line and the rear scapular line. The strain distribution and damage of the spleen under different conditions were observed. The simulation results were compared with the clinical cases of spleen rupture to analyze the mechanism of spleen injury.
objectiveThe damage location and strain distribution of the spleen could vary under different conditions. Due to the special anatomical location of the spleen, a blunt impact at the speed of 4-8 m/s on the front side did not easily cause spleen injury, and the strain was distributed mainly in the front of the spleen and the spleen hilum; a similar blunt impact on the left side was likely to cause spleen diaphragmatic surface injury, the splenic visceral surface could be injured by the compression of the medial tissue and organs and the traction of the splenic pedicle, and the strain was distributed in the spleen diaphragmatic and visceral surfaces; an impact on the back side was likely to cause injuries in the posterior portion and hilum of the spleen, and the strain was mainly concentrated in the injured area.
objectiveBlunt spleen injuries caused by punches on the abdomen are mostly caused by direct impact on the ribs, the compression by the surrounding tissues and organs and the traction by the spleen pedicle.
